COFFEE AND PEANUT ROASTER.

SPECIFICATION forming part. of Letters Patent No. 340,289, dated April 20, 1886.

Application filed August 10, 1885. Serial No. 171,057. (X n1 tlc'l) To all whom it may concern:

Be it known that I, CHARLES L; Conn, of Bushnell, in the county of McDonough, in the State of Illinois, have invented an Improved Coffee and Peanut Roaster; and I do hereby declare that the following is a-full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure 1 represents a plan view of the roaster; Fig. 2, a-scctional elevation of the same at X X in Fig. 1; Fig. .3, a cross-section at Y Y in Fig. 1; Fig. 4, a perspective view of the inven- [5 tion.

This invention is in the line of coffee and peanut roasters, in which the roasting-cylinder is adapted to be revolved and to be withdrawn horizontally from the furnace.

The particular results which I desire to secure by this construction relate, first, to an improved means for adapting the roastingcyliuder to be withdrawn from the furnace; second, to an improved stirrer for the roasting-cylinder; and, third, to a steam-generator.

My means for enabling the roasting-cylim der to be withdrawn from the furnace consists, essentially, ,in mounting said cylinder upon a horizontal rod held rigidly at one end alone.

My improved stirrer consists of reverse spiral ribs affixed to the interior cylindrical surface of the roaster, and of the combination with these of diagonal webs. Y 5 My means for increasing the steam generation of the boiler which runs the steam-whistle and warming-tray consist-s in arranging said boiler at one end of the furnace between the end wall and a partition separating the same 40 from the roasting-cylinder.

In the drawings, FF are the lateral walls of the furnace, and F F the end walls thereof. Through the end wall Fis a circular opening, 0, designed to permit the passage through the 5 same of the roasting-cylinder A. Concentric with said opening, but projecting rigidly from the end wall F opposite thereto, is the rod R, upon which the roasting'cylinder A is mounted. By means of the partition I, separating the roasting-cylinder from the boiler-chamber, said rod R is held'with greatly increased firnr ness. The roasting-cylinder Acan be mounted directly upon the rod R by means ofsuitable holes made through the ends of said cylinder, and to support the cylinder when drawn almost out of the furuace'a diametricalprop, R, can be secured in the cylinder, as shown in Fig. 2; but I find it to be much better to provide a tubular hub, T, for the cylinder, in which said rod It may slide. The outer end of said tubular hub is prolonged somewhat beyond the end of the cylinder, and to said pro jecting extremity is secured the crank-arm If. My usual mode of securing said crank-arm in place is by passing it partially through the tubular hub. as shown in Fig. 2. Said tubular hub and roasting-cylinder beingrigidly fastened together, the turning of said crankarm revolves the roasting cylinder also. By means of this telescopic arrangement of the hub 'and rod theroasting-cylinder A can be almost entirely withdrawn from the furnace and still be supported horizontally.

, To keep the roasting cylinder in place in the furnace, and also to prevent the escape of heat from the latter, I hinge the half-doors D to the outside of the end wall F, making the semicircular notches D in the edges of said doors, for the. purpose of leaving room for the huh I to project through the same and bring the cranlearm H to the outside. A button, D", secures the two doors in place when shut. Through the side of the roasting-cylinder A is an opening closed by a suit-able door or slide, for the insertion and withdrawal oft-hecoffee or peanuts.

To enable the rotation of the cylinderA to more thoroughly mix its contents, I have designed the stirrer constructed as follows: Upon the concave interior of the roasting-cylinder I affix in pairs two or more incomplete spiral ribs, 0, one of which extends from one end of the cylinder to within a short distance of the opposite end. The other rib, O, is shorter and extends from the cylinder end not touched by the other in anopposite spiral almost to said former rib. The cylinder being revolved, the coffee or peanuts are taken up by said ribs and rolled toward their approximate junction, at which point a part of the berries are permitted to pass through, while the remainder, as the cylinder continues to revolve, are rolled back steam to blow the whistle and to keep the peaure to operate the whistle being considerably and flanged so as to permit it to readily repartition I and end wall F the cylindrical boiler N, from which extends a steam-pipe to again and finally spilled over the edges of said I nut-roasters have been constructedin which ribs. By means of this construction a quantity of peanuts is constantly being broken up into unequal masses, and thereby more thoroughly mixed and stirred. To increase this mixing of the berries, I secure within the cylinder A the diagonally diametricalwebs C,'cut away partially at the center of each to make room for the hub 'I, as shown in Figs. 2 and 3.

\Vhen the roasting-cylinder is almost withdrawn, and is supported by the rod B, there is some little strain on said rod, especially when the roaster is a large one. To diminish said strain, I form horizontal ways W on the interior of the side walls, F, and adapt the crossbar B, to the cent-er of which the hub T is secured, to rest its ends upon said ways \V. In thisway, as the roasting cylinderis withdrawn its weight, instead of being entirely supported by the rod R, is upheld more or less by said cross-bar B. Said crossbar is secured to the rear end of the tubular hub T by having the latter inserted through an opening in said bar volve, but to be held irremovably therein. By its contact with the end wall F said crossbar prevents the entire withdrawal of the roasting cylinder A, for it is only necessary for the cylinder tobe pulled far enough outto bring its door to the outside of the furnace.

To provide steam for warming the tray in which the roasted peanuts are kept, I secure within fire box or chamber M, between the the double bottom of said warming-tray. Di rectly under said boiler N, within the firechamber M, and but a few inches from the bottom thereof, is placed a grate upon which to build the tire for raising steam in said boiler. Thus the operator can at his pleasure raise nuts warm without firing directly under the roasting-cylinder. The intensity of heat required for keeping up sufficient steam-pressgreater than that usually required for the roasting of the peanuts, there would otherwise be great danger of burning the peanuts, as

well as a lack of economy in theuse of fuel.

I am aware that prior to my invention peal the. roastingcylinders were adapted to be withdrawn horizontally from the furnace; but, so far as I am aware, none have been constructed to slide upon a rigidly-projecting rod, as is mine.

' \Vhatlclaim as myinvention, and for which I desire Letters Patent, is as follows, to wit:

1. In a coffee and peanut roaster, the combination, with the furnace having an opening through one end thereof, the rod projecting rigidly from the end thereof opposite to said opening, the tubular hub loosely mounted upon said rod, and the roasting-cylinder fixed on said hub, of the ways V, fixed to the lateral walls of said furnace parallel to said rod, and. the crossbar B, loosely secured to said tubular hub and having its-ends resting upon said ways, substantially as specified.

2. In a coffee and peanut roaster, the combination of the furnace having one or more auxiliary furnace-chambers, the steam-boiler in one of said chambers, the warming tray situated upon the furnace, and a pipe for conveying steam from the boiler to the tray, sub stantially as and for the purpose specified.

3. In a coffee and peanut roaster, the combination of the furnace having the auxiliary furnace chamber, the steam boiler in said chamber, the warming-tray located upon said furnace, the whistle, and pipes for conveying steam from said boiler to said tray and whistle, as and for the purpose set forth.

4. In a coffee and peanut roaster, the combination of the furnace having an opening through one end thereof and the transverse partition near the other end of the furnace, of the rod passing through said partition, and fixed to the adjacent end of the furnace, and having no othersupport, and the roasting-cylinder mounted upon said rod, as and for the purpose specified.

5. The combination, with the roasting-cylinder, of the incomplete spiral ribs A A, as and for the purpose specified.

In testimony that I claim the foregoing invention I have hereunto set my hand and seal this 27th day of July, 1885.
